Vector drawing plugin for Leaflet

Leaflet.draw

Adds support for drawing and editing vectors and markers on Leaflet maps.

Supports Leaflet 0.7.x and 1.0.0+ branches.

Please check out our Api Documentation

Leaflet.draw 0.2.0 changes a LOT of things from 0.1. Please see BREAKING CHANGES for how to upgrade.

## Customizing language and text in Leaflet.draw

Leaflet.draw uses the L.drawLocal configuration object to set any text used in the plugin. Customizing this will allow support for changing the text or supporting another language.

See Leaflet.draw.js for the default strings.

E.g.

    // Set the button title text for the polygon button 
    L.drawLocal.draw.toolbar.buttons.polygon = 'Draw a sexy polygon!';
    
    // Set the tooltip start text for the rectangle 
    L.drawLocal.draw.handlers.rectangle.tooltip.start = 'Not telling...';
## Common tasks

The following examples outline some common tasks.

The following example will show you how to:

  1. Change the position of the control's toolbar.
  2. Customize the styles of a vector layer.
  3. Use a custom marker.
  4. Disable the delete functionality.
    var cloudmadeUrl = 'http://{s}.tile.cloudmade.com/BC9A493B41014CAABB98F0471D759707/997/256/{z}/{x}/{y}.png',
        cloudmade = new L.TileLayer(cloudmadeUrl, {maxZoom: 18}),
        map = new L.Map('map', {layers: [cloudmade], center: new L.LatLng(-37.7772, 175.2756), zoom: 15 });
    
    var editableLayers = new L.FeatureGroup();
    map.addLayer(editableLayers);
    
    var MyCustomMarker = L.Icon.extend({
        options: {
            shadowUrl: null,
            iconAnchor: new L.Point(12, 12),
            iconSize: new L.Point(24, 24),
            iconUrl: 'link/to/image.png'
        }
    });
    
    var options = {
        position: 'topright',
        draw: {
            polyline: {
                shapeOptions: {
                    color: '#f357a1',
                    weight: 10
                }
            },
            polygon: {
                allowIntersection: false, // Restricts shapes to simple polygons 
                drawError: {
                    color: '#e1e100', // Color the shape will turn when intersects 
                    message: '<strong>Oh snap!<strong> you can\'t draw that!' // Message that will show when intersect 
                },
                shapeOptions: {
                    color: '#bada55'
                }
            },
            circle: false, // Turns off this drawing tool 
            rectangle: {
                shapeOptions: {
                    clickable: false
                }
            },
            marker: {
                icon: new MyCustomMarker()
            }
        },
        edit: {
            featureGroup: editableLayers, //REQUIRED!! 
            remove: false
        }
    };
    
    var drawControl = new L.Control.Draw(options);
    map.addControl(drawControl);
    
    map.on(L.Draw.Event.CREATED, function (e) {
        var type = e.layerType,
            layer = e.layer;
    
        if (type === 'marker') {
            layer.bindPopup('A popup!');
        }
    
        editableLayers.addLayer(layer);
    });

You can change a draw handlers options after initialisation by using the setDrawingOptions method on the Leaflet.draw control.

E.g. to change the colour of the rectangle:

drawControl.setDrawingOptions({
    rectangle: {
     shapeOptions: {
         color: '#0000FF'
        }
    }
});

Touch friendly version of Leaflet.draw was created by Michael Guild (https://github.com/michaelguild13).

The touch support was initiated due to a demand for it at National Geographic for their Map Maker Projected (http://mapmaker.education.nationalgeographic.com/) that was created by Michael Guild and Daniel Schep (https://github.com/dschep)

Thanks so much to @brunob, @tnightingale, and @shramov. I got a lot of ideas from their Leaflet plugins.

All the contributors and issue reporters of this plugin rock. Thanks for tidying up my mess and keeping the plugin on track.

The icons used for some of the toolbar buttons are either from http://glyphicons.com/ or inspired by them. <3 Glyphicons!

Finally, @mourner is the man! Thanks for dedicating so much of your time to create the gosh darn best JavaScript mapping library around.
